The invention relates to an escape device, in particular to an escape device integrated in a window sill, which can be folded and placed on a window sill of a building as part of a window sill structure, which can be instantaneously deployed as a vehicle along the outer wall of the building when necessary Slow down.

Generally, buildings are basically designed with window sills or balconies for lighting, ventilation or landscapes. However, for security reasons, anti-theft iron windows are usually added, so that when it encounters a fire disaster, it becomes an obstacle that hinders escape. , often causing a major loss of life and property.

In order to improve the shortcomings of traditional building sills with iron bars to hinder escape, such as Taiwan Invention Patent Application No. 96146261, the inventor of the present invention previously provided a "foldable conveying device" for unfolding into an emergency. Evacuate people along the outer wall of the building to evacuate people or items. As shown in Figures 8a and 8b, it mainly comprises: at least one window sill (11') is arranged on the outer wall (10') of the building (1'); a pair of guide rails (2') are vertically arranged on the window sill ( 11') on both sides of the outer wall (10'); at least one carrier (3'), in a foldable frame structure, received in the folded state on the window sill (11'), and the carrier (3 One end of the ') is provided with a plurality of pulleys (34') and guided by the guide rail (2'); at least one power mechanism (4') is fixed above the window sill (11'), and the controlled one can drive a pair One end of the pusher device (40') makes the other end retractable, and a plurality of diverting pulley sets (65a', 65b') are pivoted on the pusher device (40'); at least one hoisting mechanism (6') is fixed Within the window sill (11'), a pair of winches (62') are controlled to be actuated, the pair of winches (62') being respectively wound around one end of a cable (61'), and the other end of the cable (61') Suspending the carrier (3') around the end of the diverting pulley block (65a', 65b'); when the pusher device (40') is extended, the carrier (3') can be simultaneously unfolded; a control unit , with the power mechanism (4') and the hoisting mechanism (6') And the like are electrically connected.

Further, the carrier (3') is composed of, for example, a plurality of longitudinal direction surface structures (3a', 3b') and a plurality of width-foldable skeletons (3d') connected to each other as shown in Fig. 8c; And, a width-foldable bottom plate (3e') is attached to the bottom of the carrier (3').

As shown in Figures 7 and 7a). According to the invention, the carrier mechanism 3 is usually folded and placed on the curtain wall 1' of the curtain wall 1 , for example, integrated into a curtain window, an escape window or a smoke exhaust window, etc., and the surface of the frame structure can be decorated with The curtain glass has an appearance that is almost identical to the curtain glass window, and even the frame structure 31, 32, 33 can be replaced with a reinforced curtain glass window frame 12. In this way, the escape device can be folded and set on the window sill of the building or the curtain building, and becomes a part of the window sill structure. When the situation requires it, it can be instantaneously deployed as a vehicle to descend along the outer wall of the building, which can occur in the fire. It is quickly used to evacuate people or valuables in the first time.

In summary, the carrier machine constitutes a diagonally folded box structure, the structure of which can be simplified, and the maximum thickness after folding is only twice as large as the frame, and the volume can be thinned, almost than the window sill of the building. The small wall thickness can improve the shortcomings of the prior art. And the carrier mechanism is composed of a three-piece frame structure which can be integrated on a general aluminum lattice window, and the appearance is almost identical to the aluminum lattice window, or the frame structure can be integrated into the curtain window of the curtain building, and escapes. The window or the smoke exhaust window is part of the window structure, and even the frame structure can be replaced by a reinforced curtain glass window frame, and the appearance is almost identical to the appearance of the curtain glass window. Further, the pusher device and the suspension descending device are integrated into one module, and the construction is easy and can be mass-produced in a standardized manner, and the construction and production costs can be greatly reduced.
